SPECIFICATION forming part of Letters Patent No. 295,554, dated March 25, 1884.

Application filed October 17, 1883.- (No model.)

To a/ZZ whom-it may concern/.-

Be it known that I, THEoDoRE HUDNUT, a resident of Terre Haute, Vigo county, Indiana, have made certain new and useful Improvements in Hominy-Mills, a description of which is set forth in the following specitltation, reference being made to the accompany-4 ing drawings, in the several figures of which like letters indicate like parts.

My invention relates to the construction of cylinders for hominy-mills, and the means for securing these blades to the cylinders, and willbe understood from the following description.

In the drawings, Figure 1 represents a side View of the cylinder, with the blades in place on the upper and4 lower plates, the blades being left oft' the, plate in front so as not to confuse the view. Fig. 2 represents a longitudinal section of the same. Fig. 3 repre` sent-s a cross-section on the line x so, Fig. 1. l Fig. 4 is a front view of one of the blades,V with the open slot vertical; and Fig. 5 represents a front view of one of the blades, with the open slot in a horizontal position.

C is a wooden cylinder with four squared sides, to each of which the iron plate p, having projections or lugs Z, is attached by screws or bolts. The corners of the cylinder are dressed oft', oas shown in Fig. 3, and the dat surfaces thus formed are covered for the purpose of balancing the cylinder, by beveled plates bp; or pieces of metal f are inserted for the purpose, as shown in Fig. 3, where two of the corners are covered by the plates bp and two are filled with metal, the result in either case being similar-viz., the wooden cylinder at these points is balanced or weighted, so that it will run true while in operation. Through the length of this wooden cylinder C runs the iron axis or shaft a, squared in the wood, but turned round at either end for journals. The plates p have lugs Z projecting outward at regular intervals of distance through holes, in which a threaded rod, sr, -is passed loosely, this `rod being long enough to pass through all the lugs. This rod is threaded to receive set-nuts n, one of which is `set at either end" of each of the lugs l and works against a washer or loose plate, wp. Between this washer-plate and the end of the lug the tooth or blade b is set, the open slot allowing the blade to pass the rod sr until the latter rests4 tightened upon the rod sr against the plate wp, and the tooth is held firmly in position for work. If the tooth becomes dull or broken, by loosening the nut, it may easily be removed without disturbing any one ofthe others, and in this respect my device has a great advantage over machines whose blades cannot be separately removed. Again, the form of the blades b isa great improvement over those having a narrow shank, for at these narrow places the blade is almost sure to break, while my blade is of uniform width throughout and of uniform strength. 'Ihe slight curve of the cutting edge of my blade is better than a shorter curve, for the latter wears away more rapidly and sooner comes to a point, and is rendered useless. The ligures 1, 2, 3, and 4 upon the cylinder in Fig. 1 serve to indicate the relative points where the blades are placed on the four sides, these points being so relatively spaced that between each pair of lugs on the same plate the spiral around the cylin-` der is broken, and this prevents the crowding and packing of the grain at one end of the cylinder. This always occurs where the con- -tinuous spiral is not broken, and the result is that very soon the cylinder is so tightly packed that the belt will fly off, the cylinder stopped or burst.

The devices here shown and described are improvements upon those shown in Reissued Letters Patent No. 10,057, granted me on the 7 th day of March, 1882.

Of course it will be understood by all those familiar with the art of constructing or operating hominy-mills that the devices here shown and described are placed inside a hollow casing, having an opening into which the grain is poured; but this casing is no part of my new invention, and therefore need not be here described.

What I claim, and desire to secure by Letters Patent, is the following:

roo

1. The Wooden cylinder C, having square sides and mounted on axis a, the metal plates p, adapted to be secured to the squared sides ofthe cylinder, and provided with lugs Z, integral with the plates, and set at such distances apart as to break a continuous spiral from one end of the cylinder to the other, all combined substantially as described.

2. The Wooden cylinder C, having squared sides and mounted on axis a, the metal plates p, provided with lugs Z, integral with the plates, adapted to be secured to the sides of the cylinder, and balancing devices secured at the corners of the cylinder, all combined substantially as described.

3. The plate p with lugs Z, adapted to receive the rod sr, in combination with such rod and setnuts n, substantially as described.

4. The plate p with lugs Z, adapted to receive the rod sr, in combination with such 2o rod, the set nuts n, Washerplates wp, and blades b, substantially as described.

5. The cylinder C, mounted on axis a, the plates p, having lugs Z, the rods sfr, set-nuts n, and blades b, all combined substantially as described. v

6. The cylinder C, mounted on axis a, having plates p, provided with lugs Z, the rods sr, passing through said lugs, the vset-nuts nl, Washerplates wp, and blades b, with open slots, all combined substantially as described.

In Witness whereof I have hereto set my hand this 12th day. of October, A. D. 1883.

THEODORE HUDNT.
